The Schedule referred to in these Letters Patent and making partici' thesame.

To all whbnt t't may conce-rn: n Bc it known that I, SAMUEL 1t.ScoGGINs, of Baltimore, in the county of Baltimore and State ofMaryland, have invented 'a'new and Improved Refrigerator;

and I do hereby declare the following to be afull, clear, and exactdescription of the same, reference being had tothe accompanying drawingmaking 4a 'part of this specification,l in which- "Figurel is a verticalsection cutting through 'the 'linewvin g.2; .i f i Figure'Z isatransverse section lcutting through `line'y y in lig. 1; and

Figure 3 is a horizontal section, made oblong, and

provided with air iuternalchamber for the freezing materiah Thisinvention consists `inthe construction, hereinafter described, ot` adoublefcase oi' metal, and the arrangement of it within a woodencase,.inj snc'h a manner that a freezing-mixture, such as salt and ice,may be introduced into the space between the interior and exterior metalcases, or in one or more metal chambers placed within the double case,and that the water produced in the space between the metal cases by thethawing of the freezing-mixture, or water produced in the interior ofthe metal case from any causefwhat-l ever, may rnn oi through pipesattached tothe double ease,4 and penetrating the bottom of the woodencase, the objectof the invention being to produce areii'igerator thatwill keep food, fish, &c.,' in a frozen condition.y

i Inthe drawing- 1 a is the outer wooden case, provided with theholes band c, and the hinged cover 1l.

i The hole b is forV ventilation. The hole c for the reception of thepipes attached to tne double case e.

fis the outer metal case, provided with a hinged cover, g; Itsbottom,`h, consists of four downwardly converging sides, and `isprovided with `the pipe t'.

lThe bottom j of the inner case kcorresponds in i shape with thebottomof th-e case f, and is provided with the pipe l, whichis`looselysheathed within the pipe The sides of `the casek, fromy thepoint m `downward, are parallelwith the .sides of the case f. From thepoint '1n upward, they converge and meet the l `cover g,'in`iorder thatthe freezing-mixture may be more` readily introduced intothecompartments made by the partition vo.

The cases f and k are formed into a'double case, n, and made to maintaintheir relative ,positions by bemediately around the pipe l.

p are frames, introduced when food only is desired to be kept. They areused generally in the smallersized refrigerators. The food is passeddown the vertical center ofthe refrigerator and placed upon the framesp. Y v

In keeping large quantities of {ish-packed closely together, there isdanger that those in the center of" the mass will becomev decayed. Inorder to prevent this, I place one or more chambers, q, in the case a,shown inl iig. 3, pack the lish around the chamber, and ll thecompartments, between the partitions vand the chamber or chambers q,Vwith the freezing-mixture.

In a. refrigerator four feet square, I leave not more than two (2)inches space between the cases f audit. In larger ones the space shouldbe in proportion.

I construct the' metal cases of galvanizedsheet metal, and placea.snitable frame within the outer wooden case a, for the bottom of the.metal case to. rest upon.

The .outer case a and double caseta, may be constructed eitherrectangular o r cylindrical in form. The walls of the case a maybcmadeof several thick nesses, the several thicknesses being arrangedeither in Contact, or with an air or felt-chamber betweendownwardly-converging bot-toms hf and j, thepipes iV and l, andpartitions o, the frames p, one or more vchambers q, and theinolosingwoodenca'se a, provided with holes b and c, all constructed andcombined substantially as and for thepurpose hereinbefore specified.

SAMUEL SOOGGINS.
